The new generation UltraCap LPS-1.2: USER IMPRESSIONS and QUESTIONS thread

Recommended Posts

Hi. This is a basic question but do you need to turn off the unit before switching the voltage. 

 

I'm comparing two devices, with different voltage requirements. I'm been turning off the LPS1.2 while I turn the dial for fear of damaging the unit. However, i need to go back and forth as quickly as possible, and turning it off means waiting for the caps to charge.

I'll let Alex answer the direct question, but as someone that has generated the magic "Oh Shit!" white smoke one too many times, I've developed the discipline of checking the voltage of variable supplies with a multi-meter before plugging them into a new device.  There is definite risk to moving quickly when switching supply voltages and devices quickly!

For me, I once had: fire, actual real, mad scientist in the basement lab, fire. 

 

One of the costs of endless tinkering, but it's not something I ever would like to see again.

Hi Edward:

Technically you do not have to power off the UltraCap unit before changing output voltage setting--though we prefer you do. But not doing so won't accomplish what you want anyway: Changing the setting of the blue output voltage switch puts the LPS-1.2 into a full reset and you'll have to wait. There are lots of states of voltage status that get checked and certain things must discharge--all in the name of self preservation by the UltraCap. It's prime directive is to survive! x-D

Welcome to Audiophilestyle 

According to Qutest website, it uses micro USB, so you’re correct there. Uptone use 2.1 mm, so that’s correct to. 
 

You may consider this. 😀

Thank you for the welcome and the advice. Will certainly take a look

wondered if this was the correct adapter


technically... yes, it is

though Qutest's micro USB power port is inside a "tiny-ish" recess so that one might not fit

look for adapters with a lesser amount of "plastic around the plug" ;)

You are correct, though the one @JD123 linked to will fit the chassis recess of the Qutest.  I know because that is the exact one we stock—to toss in free upon request—for UltraCap buyers with Qutest. :D

Hi, I'm getting a kingrex uc384 converter that's supposed to draw 7.5v 200mA.

I'm already using a lps 1.2 to power a microrendu so I thought maybe, if I'm lucky, the lps 1.2 would be able to power both?

 

I guess there's only one way to find out, but would it be safe to try? I've fried a psu while powering two devices a while back.. so thought I'd ask before trying 😉

The power consumptions your microrendu and kingrex uc 384 converter it is way below the current capability of lps-1.2. You should be ok to powering both device's.

   I am using my single lps-1.2 to powering microrendu, singxer F-1 usb to spdif converter, wyred for sound remedy digital recklocker and 5 ldovr lt3045 boards with good success.

Hi there

did anyone compare LPS 1.2 to JS-2?

I have IFI PRO IDSD. I want to upgrade it.

Shouild I buy Ultracap or Js-2?

Input voltage (Pro iDSD):

DC 9V/6.7A – 18V/3.35A

 

LPS 1.2 won't power the unit.

I believe you refer to LPS-1. 
as I read in the manual - LPS-1.2 offers 5V, 7V, 9V, 12V. But only 1.1A

no -- he meant the lps-1.2.  as he said, it won't handle it -- can't provide enough current.

Ok.  I understand. 
I read in IFI PRO IDSD manual: “We strongly recommend the use of the included iPower Plus 15v. It offers the latest in power supply technology and is better and cleaner than any battery or aftermarket linear power supply”. 

What do you think?

Will I hear significant improvement if I purchase and connect Js-2?

There are a lot of iFi Pro DSD users with JS-2s. Check the JS-2 thread.  Here is the recent post of another Pro DSD/JS-2 owner:

My 1.2 is very hot when running. I have measured 58 C today with a Seek Thermal

 

i have designed a heat sink that should improve things a bit but I would first like to understand whether the current level of temperature is normal or not.

 

cheers,

bernard

If the output load on the UltraCap LPS-1.2 is near the unit's 1.1A limit on a continuous basis, then yes, the temp you measure is normal.

Suddenly the sonore optical module doesn’t seem to want to work when powered by the LPS 1.2 on the 5 volt setting.  The green power light on the optical module flashes but doesn’t stay solid green.  Its been working flawlessly for weeks but suddenly this.  So what happening now is that the green power light on the optical module flashes green constantly and the ethernet connection on the optical module doesn’t light up at all.  
 
I’ve tried rebooting/restarting just about everything.  I DO have another 5 v power supply around but I MUCH prefer the sound with the LPS 1.2 (as I posted previously).  The LPS 1.2 was purchased around June of 2018.
 
Whats the problem?
